Description

Method and apparatus for displaying connect guide between device and device

The present invention relates to a method for guiding a connection between a video device and an external peripheral device, and more particularly, to a method and apparatus for displaying a connection guide between devices for displaying a connection between the video device and an external peripheral device on an on-screen display (OSD) menu screen.

In the conventional connection between a video device and a peripheral device, a connection between a television (TV) and a video cassette recorder (VCR) is mainly used. At this time, the connection between the TV and the VCR is a method of connecting a high frequency (RF) output terminal of the VCR and an RF input terminal of the TV, or composite video and audio left / right (using an external input terminal, that is, an RCA type jack). L / R) and the like. To make this connection, users often have to look at the manual and make the connection. If the user loses the manual, this simple connection is often difficult.

In recent years, due to the increase in TV functions, peripheral devices capable of processing inputs by TVs are not only VCRs but also cable boxes, digital versatile discs, digital terrestrial broadcasting, satellite set-top boxes, gemstars, and PCs. There may be more peripherals in the future.

As the number of peripherals continues to grow, users will experience many difficulties connecting to TVs and peripherals, and the user manual will become more complex to account for such connections. In particular, the manual is easy to lose, and if the user loses the manual, it is very difficult to connect the peripherals.

Therefore, another conventional method of showing the connection between a TV and a peripheral device is to enter it through a complex list of questions such as whether the peripheral connected to the user is in the initial setup menu of the TV set, whether it is a VCR, cable box, DVD, ... For example, there is a way to change the internal configuration of the system according to the wiring diagram.

However, if the user wants to see the connection status between the peripheral device and the TV other than the peripheral device selected by the user, the user can see the connection diagram only after inputting the question list from the beginning. This method is difficult for the user to see the overall wiring at a glance, and to check what peripheral devices are selected, they have to go back to the previous question list and start from scratch. In particular, in the case of simply trying to figure out how the TV is connected to the peripheral device, the above-described method is rather complicated and inconvenient for the user.

The present invention is to solve the above problems, an object of the present invention is to display on the OSD menu screen the connection diagram connecting the video device and the external peripheral period selected by the user so that the user can visually easily recognize without a manual The present invention provides a method and apparatus for displaying a connection guide between devices.

In order to achieve the above object, a method of guiding a connection between devices according to the present invention includes displaying a menu item including items on the screen by names of external peripheral devices connectable to the video device by a menu selection device such as a remote controller. And selecting, by the menu selection device, all connection relationships between the external peripheral device and the video device corresponding to the selected item by OSD processing and displaying on the screen. Characterized in that made.

The connecting display step may include a connection line between an input / output terminal board of the video device and a terminal board of an external peripheral device, and a corresponding terminal of an input / output terminal board of the video device and a corresponding terminal of an external peripheral device terminal board corresponding to a selected item. It is characterized by displaying.

The menu item, the input / output terminal board of the video device, and the terminal board of an external peripheral device are simultaneously displayed on one screen.

The apparatus for displaying a connection guide between devices according to the present invention comprises a storage unit for storing OSD menu items, data for displaying a connection relationship between the video device and an external peripheral device, and a system program, by using the system program. A menu selection device for displaying on the screen menu items consisting of each item by names of external peripherals that can be connected to a video device, moving a cursor between the displayed menu items, and selecting a desired item; If any one of the displayed menu items by the device is selected, and comprises a display for displaying on the screen by the OSD processing all the connection relationship between the external peripheral device and the video device corresponding to the selected item .

The present invention displays a connection diagram connecting an external peripheral device, such as an antenna, a VCR, a cable box, a DVD, and a PC, to a video device such as a TV on the screen of the video device through an OSD menu, so that a user can use the video device without a manual. This is to make it easy to know how to connect the TV and peripherals.

Other objects, features and advantages of the present invention will become apparent from the following detailed description of embodiments taken in conjunction with the accompanying drawings.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating an example of a TV receiver to which the present invention is applied. The key signal attached to the TV is input to the microcomputer 103 through the key receiving unit 101, and the key signal using the remote controller is infrared. (IR) is input to the microcomputer 103 through the receiving unit 102. The IR / key decoding unit in the microcomputer 103 interprets the code of the key signal and outputs the code to the digital processing unit 109 through a protocol line.

The digital processing unit 109 includes a central processing unit (CPU) 112 that executes the entire system and embedded programs, and the CPU 112 executes a corresponding command according to a key code transferred to a protocol line.

In this case, various peripheral devices may be connected to the TV receiver. For example, a National Television Standards Committee (NTSC) antenna, an Advanced Television Systems Committee (ATSC) antenna, a first VCR input terminal J1, a second VCR input terminal J2, a third VCR input terminal J3, HD The peripheral devices may be connected through a High Definition Distribute Sample Scrambler (DSS) input terminal J4, a DVD input terminal J5, and a Video Graphics Array (VGA) input terminal.

Therefore, when several peripheral devices are actually connected, the selection and operation of the connected peripheral devices should be able to be performed.

In this case, keys for selecting the peripheral devices are assigned to a key input unit such as a remote controller. For example, one key may be assigned to one peripheral device, or a plurality of peripheral devices may be assigned to one key. .

If a plurality of peripheral devices are assigned to one key, the peripheral devices may be sequentially selected by repeatedly inputting the key. That is, the key code value corresponding to the key pressed by the user is input to the microcomputer 103 through the key receiving unit 101 or the IR receiving unit 102.

In this case, assuming that the selected peripheral device is connected to the TV through a connection line (or cable), a signal of the selected peripheral device is input to the TV through the connection line and displayed on the screen after a series of processes are performed. .

For example, if the key input by the user is an antenna key, one of the input signals from the NTSC antenna and the ATSC antenna is selected. If the user inputs the antenna key while the analog video signal input through the NTSC antenna is currently displayed on the TV screen, the digital video signal input through the ATSC antenna is displayed on the screen. The opposite is also true.

In addition, when the key input by the user is a video key, one of the composite video signals input from the first VCR input terminal J1, the second VCR input terminal J2, and the third VCR input terminal J3 is selected. If the video key is pressed while the video signal input through the first VCR input terminal J1 is currently displayed on the TV screen, the video signal input through the second VCR input terminal J2 is displayed on the TV screen. Is displayed. When the video key is pressed again, a video signal input through the third VCR input terminal J3 is displayed on the TV screen. Subsequently, when the video key is pressed, video signals input through the first VCR input terminal J1, the second VCR input terminal J2, and the third VCR input terminal J3 are sequentially displayed on the TV screen.

When the key input by the user is a DVD key, a DVD (YCbCr) video signal input through the DVD input terminal J5 is displayed on the TV screen.

The video signal of the peripheral device is displayed on the screen in the above-described manner with respect to other peripheral device selection keys.

On the other hand, looking at the path of the input signal selected by the peripheral device selection key as described above, for example, the first VCR input terminal J1, the second VCR input terminal J2, the third VCR input terminal J3 The composite video signal of any one of the composite video signals input through the A / V switching unit 105 is selected. The A / V switching unit 105 is controlled by a peripheral device selected by a user, that is, a source selection key.

The composite video signal selected by the A / V switching unit 105 is output to the digital comb filter (DCF) 106 to perform luminance / color (Y / C) separation, and the separated Y / C signal is NTSC. The decoder 107 separates the brightness information Y and the color information U / V and outputs the same to the video chroma processor 108. Here, the video signal input to the tuner 104 through the NTSC antenna is also input to the VCP 108 through the above process.

In this case, the VCP 108 can accept NTSC, HD-DSS, VGA, and DVD signals, select one of several input signals according to the user's source selection, and then convert the analog YUV signal through the SEL_out terminal to the digital processor 109. ) Is output to the A / D conversion unit 110. If there are more peripherals that can be connected to the TV, the signal that can be accepted by the VCP 108 also increases.

The A / D converter 110 of the digital processor 109 converts the analog YUV signal into a digital YUV signal and outputs the analog YUV signal to a video decoding processor (VDP) 115.

On the other hand, the digital video signal input through the ATSC antenna is input to the transport demultiplexing and decoding unit in the CPU 112 through a video decoding process for decoding the demultiplexed and separated video bitstream separating the video bitstream, the VDP Is output to 115. In this case, the DRAM 113 is used for decoding the video, and can be generally divided into write and read bit streams, read data necessary for motion compensation, write decoded data, and read data to be displayed. The flash ROM 114 stores programs to be executed in the CPU 112, characters for the OSD, and graphics fonts in the form of bitmaps.

Accordingly, the VDP 115 may receive an externally input video signal (for example, an output of the A / D converter 110 or a video signal input and decoded through an ATSC antenna) and the flash ROM 114. The OSD menu generated by the bitmap stored in the synthesizer is synthesized, converted into a YUV signal, and then output to the VCP 108. The VCP 108 converts the YUV signal into an RGB signal and displays the same on a display unit 116 such as a TV screen.

Here, the OSD-processed screen may be displayed on the screen as a text or graphic form, and the OSD-processed screen may be displayed thereon.

Meanwhile, the Easy (EZ) hook-up menu screen proposed by the present invention is also displayed on the TV screen through the OSD processing to show how to connect the TV to an external peripheral device.

In this case, the EZ hook-up menu screen showing the connection between the jack panel of the TV and the jack panel of the external peripheral device may be displayed through a sequential selection process in the OSD menu screen, or a selection consisting of at least one key. After assigning a key for directly entering the EZ hook-up menu screen, the device may be directly displayed without an intermediate process through the assigned EZ hook-up menu key.
